With regard to the two degrees in eight seconds...
I suggest that this be read again, for clarification.
Here is the bit from FCOM DSC 27-20-10 Normal Law - Pitch Control - Flare Mode.
"The system memorizes the attitude at 50 ft, and that attitude becomes the initial reference for pitch attitude control. As the aircraft descends through 30ft, the system begins to reduce the pitch attitude, reducing it to 2deg nose down over a period of 8 s."
If it was "by" 2deg over 8 seconds, why would the system bother to memorize the pitch attitude at 50'?
